Given numbers are 221, 873, 655, 497
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 873) = 192933
GCD(221, 873) = ( 221 x 873 ) / 192933
= 221 / 873
= 221
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
So, Greatest Common Divisor of 221, 873, 655, 497 is 1
